Pinnacle Speakers Rhino-Fiftenn, Owner'S Manual

• 

Adjust the PHASE switch on the subwoofer’s control panel to determine which position sounds the most 

natural.  The difference should be most audible in the mid-bass.  If you cannot detect a difference, leave 

the PHASE switch in the 0° (in-phase) position. 

• 

If you have placed your subwoofer's Crossover Bypass switch in the OFF position adjust the 

CROSSOVER knob and determine what position sounds best.  This feature controls the output level of 

the mid and upper bass frequencies.  Please note that if you have put your subwoofer's Crossover 

Bypass switch in the ON position, due to the low pass filter already in your receiver, the subwoofer's 

crossover control is unnecessary, will have no effect, and its position can therefore be ignored. 

• 

The best VOLUME level, PHASE switch and CROSSOVER positions will mostly be determined by your 

room acoustics and the mid and upper bass frequency response characteristics of your front speakers.  

The source material will also play a significant role as its bass level may vary considerably. 

• 

After your initial adjustments you may want to go back and “tweak” these controls.  Their effects are 

acoustically interrelated.  Re-adjusting them may be necessary to obtain optimal performance.  

Generally, once you are satisfied with your subwoofer's settings, you can use your receiver’s tone, 

equalizer, volume and subwoofer output level controls to optimize your whole system’s performance. 

VERY IMPORTANT! 

• 

If you have a Dolby Pro-Logic Home Theater system, make sure that your receiver’s center 

channel mode is in the NORMAL position.  This will ensure that all low bass information is sent 

to your subwoofer. 

• 

If you have a Dolby Digital or DTS Home Theater system, make sure that you have correctly 

configured your receiver's Bass Management System so that all of your speakers are properly 

categorized as either  SMALL or  LARGE (please note your receiver's terminology may differ).   

This will ensure that all appropriate low bass information is sent to your subwoofer.  As a 

general rule, a speaker with an 8" or greater diameter woofer may be considered  LARGE.  

Conversely, a speaker with a woofer less than 8" in diameter may be considered SMALL.  Please 

note that the bass output of a dual woofer speaker could be comparable to that of a larger single 

woofer speaker.  Example: A dual 6.5" woofer system would generally be considered  LARGE 

since its woofer area approximates that of a single 10" woofer system.
